Feasibility and early toxicity of intraoperative radiotherapy for breast cancer using the papillon + system: First results.

Background And Purpose: Breast intra operative radiation therapy has been evaluated with different systems delivering 20-21 Gy with treatment times around 30 min. Papillon + Contact X-ray machine was designed to produce a 50 kVp beam with a high dose rate ≥ 15 Gy/minute. A pilot study with the first prototype was conducted in Nice.

Factors Involved in Delaying Initiation of Adjuvant Chemotherapy After Breast Cancer Surgery.

Background: Delays in initiating adjuvant chemotherapy after breast cancer surgery seems to have an impact on patients' risk of relapse and their survival rate. The aim of this retrospective study was to identify factors delaying initiation of adjuvant chemotherapy after breast surgery.

Material And Methods: All patients undergoing surgical treatment for mammary cancer between June 2014 and June 2015 and receiving adjuvant chemotherapy were selected retrospectively.

[Is preoperative axillary radio-cytology justified after ACOSOG Z001?].

Introduction: Invasive breast cancer without clinical adenopathy (cN0) is currently explored by the sentinel node (GS) technique, except in the case of positive preoperative radio-cytological screening, where axillary curage (CA) remains systematic from the outset. Since the publication of the ACOSOG-Z0011 trial, abstention from CA is possible in patients presenting less than three metastatic GS. As a result, the value of axillary radio-cytological screening is being questioned as it could potentially lead to axillary surgical over-treatment.

[Impact of COVID-19 pandemic on breast and gynecologic cancers management. Experience of the Surgery Department in the Nice Anticancer Center].

Introduction: During the COVID-19 pandemic, the containment measures and the recommendations of several societies in oncology may have impacted the request for initial care for cancers.

Methods: In this monocentric retrospective study, the number and the characteristics of patients received for a first consultation for a breast or gynecologic tumor were compared between the containment period and a control period. The times from diagnosis to treatment and the type of initial care were compared too.

[Preoperative breast imaging review: Interests and limits of specialized validation in oncology].

Objectives: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients.

Materials And Methods: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images.
